MACHINE FOR TREATING SEVIAGE, REFUSE, OR THE LIKE.

981,445. Specification of Application filed February 2 To all whom itmay concern:

Be it known that we, ABRAHAM MARTIN, of 131 Rue du Faubourg Saint-Denis,mechanical engineer, and ADOLPI-IE \VI-IITGOMB, of 35 Avenue Hoche,landlord, both in the city of Paris, Republic of France, have in venteda Machine for Treating Sewage, Refuse, or the Like, of which thefollowing is a full, clear and exact description.

The present invention relates to a machine for the treatment of sewage,refuse or the like, and has for its object to break up the materialsunder treatment, to pulverize them, to work them up and to dry themwithout permitting the escape of bad smells or odors.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

In the accompanying drawings, Figure 1 is a side elevation of a machineconstructed according to the present invention. Fig. 2 is an endelevation thereof. Fig. 3 is a vertical transverse section taken on theline AA of Fig. 1. Fig. at is a vertical longitudinal section taken onthe line BB of Fig. 2. Fig. 5 is a similar view to Fig. 3 illustrating amodification. Fig. 6 is an elevation showing a number of drums arrangedin series, the view being on a reduced scale.

In the several figures like parts are indicated by similar letters ofreference and all said figures are drawn to an equal scale.

Referring to-the drawings, the machine comprises a rotatable drum athaving interiorly a cylindrical form as shown in Fig. 3 or a prismaticalform as shown in Fig. 5 and provided with hollow trunnions Z) c mountedin bearings carried by two standards (Z 6. Within this drum are arrangedheavy weights each constituted, for example, by a hollow cast iron ballloaded with lead or other heavy material of any desired weight.

In the periphery of the drum is formed an opening for charging anddischarging the machine and this opening is normally kept closed by adoor 9 having two leaves for example.

The weights 7 are retained within the drum in the open position of thedoor 9 by bars h as shown in Figs. 3 and 5.

The trunnion b is connected to a :tan 2' which drives air (if desiredsaturated with an antiseptic) into the interior of the drum Let P n?atented J an. 10, 1911.

I a, while the apparatus in in operation. The

second trunnion c, from which the air which traverses the drum (4issues, is connected to the air admission trunnion of a second drumidentical with the drum a, while the trunnion at which the air issuesfrom this second drum is connected with the air admission trunnion of athird drum and so on. The air exit trunnion of the last drum may beconnected by a conduit, with any suitable firegrate.

The materials to be treated; sewage, re;t use or the like, are shot intoeach drum, the door 9 being opened, through a hopper beneath which isbrought into position the opening of the drum which latter held in thatposition by any suitable arrest-ing means. When the charging operationis completed the door 9 is closed and the apparatus put in action. Tnconsequence of the movement of rotation imparted to the drum a, theweights f constantly roll upon the interior of the latter, crushingbeneath them the material which carried around in the movement ofrotation of the drum is constantly thrown in front of the weights. Byits successive--passages under the weights 7', the material is broken upand finally pulverized. During the operation of breaking up, the tan 2'drives air through the trunnion Z) into the interior of the drum, andthus air passes through the moving mate rials, dries them, draws with itthe combustible gases and bad odors and separates the materials duringtheir treatment, and said air and the gases drawn with it leave by thetrunnion c as above pointed out. The duration of the operation will beabout 30 minutes, but it will be understood that this time should bemodified according to the materials to be treated. iVhen the operationis concluded the drum (4 is arrested in the position represented in thedrawing, the door 9 is opened and the material, which has beenpulverized, dried, and deprived of its bad odors is discharged.

The apparatus is economical and hygienic; sinceon the one hand, iteffects, at one operation by a very simple arrangement the breaking up,pulverization, drying and de-' odorization ot' the materials while onthe other hand, the germs of fermentation and the gases separated fromthe materials dur ing treatment cannot be diiiused into the atmosphereof the works but are carried away and burned as above pointed out.

Under these conditions the atmosphere of the works is not infected as isat present the case with works where refuse is treated.

The machine may be constructed in any form or of any dimensions and thedetails of construction thereof may be modified according to itsapplications.

1. An apparatus for treating sewage, ref use and the like, comprising arotatable drum, weights within the drum, means for introducing cold airinto the drum for the purpose of cooling the matters to be treated andcausing this cold air to circulate through the drum while the latter isrotating for the purpose of freeing the matters from any bad odor andgerms of fermentation, the said drum being provided with an opening inits periphery, a door normally closing said opening, and means forretaining the weights within the drum, when the door is in the openposit-ion.

2. An apparatus for treating sewage, refuse. and the like, comprising arotatable drum containing heavy balls, means for rotating the drum, afan for passing a continuous current of air through the drum while thelatter is rotating, the drum being provided with an opening in itsperiphery for the admission and discharge of the material, a doornormally closing said opening, and bars at said opening for retainingthe balls within the drum.

3. An apparatus for treating sewage, refuse and the like, comprising arotatable drum provided with hollow trunnions, one of said trunnionsbeing an air inlet trunnion, and the other trunnion being an air exittrunnion adapted for connection with a fire grate, bearings in which thetrunnions are mounted to turn, heavy balls within the drum, a fanconnected with the air inlet trunnion, the said drum having an openingin its periphery for the admission and discharge of the material, a doornormally closing said openin and means for retaining the balls in thedrum when the door is in the open position.

4. An apparatus for treating sewage, refuse and the like, comprising arotatable drum, heavy balls within the drum, the drum being providedwith hollow trunnions, supports provided with bearings in which thetrunnions are mounted to turn, and a fan connected with one of saidtrunnions for forcing cold air into the interior of the drum for thepurpose of cooling the matters to be treated and causing this cold airto circulate through the drum while the latter is rotating for thepurpose of freeing the matters from any bad odor and germs offermentation, the air passing from said drum by way of the othertrunnion.

An apparatus for treating sewage, refuse and the like, comprising aseries of drums, heavy balls within the drums, the drums being providedwith hollow trunnions mounted to turn in suitable bearings, and a fanconnected with one of the trunnions of the first drum of the series, thetrunnions of the said drums being connected whereby the air passessuccessively into and through the said drums, the air exit trunnion ofthe last drum being adapted for connection with a fire grate.

6. An apparatus for the treatment of sewage, refuse and the like,comprising a rotatable drum presenting a polygonal internal surface,heavy balls .moving freely therein, and means for introducing cold airinto the interior of the drum for the purpose of cooling the matters tobe treated and causing this cold air to circulate through the drum whilethe latter is rotating for the purpose of freeing the matters from anybad odor and germs of fermentation.

7. An apparatus for the treatment of sewage, refuse and the like,comprising a rotatable drum presenting a polygonal in ternal surface andcontaining heavy balls adapted to move freely therein, means for passinga current of air through the drum, the said drum being provided with anopening in its periphery for the admission and discharge of thematerial, a door for normally closing said opening, and means at saidopening for retaining the balls within the drum when the door is openand the drum is in the discharging position.

The foregoing specification of our machine for treating sewage, refuseor the like signed by us this 11th day of February, 1908.
